SCREEN-HINGE'.

Application tiled February 11, 1919. Serial No. 276,402.

To all whom t may concern Be it known that I, JOSEPH B. BRADLEY, acitizen of the United Statesresiding'at Miama, in the county of Dade andState of Florida, have invented new and useful Improvements inScreen-Hinges, of which the following is a specification. A i

This invention relates to hinges, and more particularly to sash orscreen frame hinges which are mounted in rabbeted' places 1n theirframes.

One of the principal objects of the 1nvention is to provide a hingewhich is" readily attached to the sash or screen frame and which permitsof the convement h anging of the sash or screen without mortising orwithout materially marring the window'` frame.

Another object of the invention is the provision of a hinge forvertically swlnging window sashes or screens 'adapted to u fit withinthe rabbet portions of window frames which will absolutely prevent thebreaking or splitting of the wood of which removed.

the sash or screen is constructed at thevpoint of attachment of the hine. Further objects and a vantages will api pear as the followingdescription is read 1n connection with the accompanying drawing whichforms a part of this application, and in which:

Figure l is a perspective view showing a detail of a window frame with ascreen hinged in the outer rabbet.

Fig. 2 is a horizontal section taken on the line'2*2 of Fig. l, and

Fig. 3 is a perspective view of the ,hinge Fig. 4 is a detail sectionalview showing the position of the hinge on a screen frame. Referring moreparticularly to the drawings 1 represents the body of the hinge whichis'eon'structed of anysuitable typeof material andis provided at itsside marginal edges 'with arallel anges 2 and -at its upper end withan'attachin'g'lip 3 lying in a plane with the body and provided with a'hole 4.- to receive a pivot be driven into the window frame 6. The bodyof the hinge is provided with separate screw or other similar fasteningdevice which is adapted to many conditions under which the hinge'may beemployed.

In using the present type of hinge to connect the screen frame to thewindow frame one hinge member is mounted upon each upper end of theframe with'the flanges 2 straddling the same and littin on the inner andouter sides thereof, as s own in Fig. 2 with the lip 3 extending abovethe screen frame so as to conveniently receive the fastening device.rIhe hinge is then attached by driving in the fastening members 8 whichpass through the apertures and enter'the wood of the frame as shown. Thescreen` frame is then fitted within the rabbet and the pivot screws ornails are driven into the wood of the window frame. The

screen thus normally hangs in a vertical position with its inner faceabutting the sash bead 9 and its lower ed e contacting with the sill l0.In practice, suitable catches are employed to hold the lower end ofthescreen from moving outwardly accidentally and as employed the screenframes are provided with a bridging strip 11 which is attached to theupper end of the screen on the inner side and extends between the sameand the outer and upper sash as shown to prevent the'ingress of flies orother insects. It is, of course, understood that this strip may beomitted and the screen hinged to the inner surfaces of the opposite sashbeads 9. In such instance a suitable stop would be provided for thelower end of the screen to contact with to limit .its inward movement.When -the lower end of the screen 1s K speeineatiqn of Letters Patent.Patented June 17, 191.9.l

pushed outwardly the upper end will 'l leave the upper sash and againcome in conl tact with it when the lower end of the screen 1s IpIulledinwardly.4

vices, attaching devices extending t erethrough and entering the Wood'of the frame, lateral imperforate flanges extendingfrom the side edgesof the body and arranged to straddle the vertical pieces of the frame towhich the bod)Y is attached and lie parallel to each other und to tliefastening devices to prevent splitting of the frame and a longitudinallyextending lip formed integrally with the body and having a centralaperture to receive a pivot member for the 10 hinge.

In testimony whereof I :1l-fix my signature.

JOSEPH B. BRADLEY.
